IMPAovEivu-:NTiN APPARATUS FOR Dls'rlLLlNe TURPENTINE, ac.

Specication forming part of Letters Patent No. 115,429, dated May 30, 1871.

necticut, have inventeda new and Improved Apparatus for Distilling Turpentine, Oils, Hy-

. i `drocarburets,`j&c., of "which the following is a 1, specificationz .i j j My invention consists in the peculiar construction and arrangement of the several parts of vmy apparatus, as willgbe hereinafter more In the accompanying drawing, Figure 1,

,Sheetl, is a side elevationof my improved apparatus; Fig. 2, Sheet 2, Vis a longitudinal g central vertical section through the same; and Figs. 3, 4, 5 and 6, Sheet `3, are detached vviews of parts of the same.

In the drawing, l represents a steam-boiler and 2 a superheater, the steam-pipe a being led forward `andbackward in the same, as

shownfin Fig. 3, Sheet 3.?` 1A still, 3," is com-V posedof two parts,`A B, the lower part being inclosed in a jacket, D, leaving a steam-space, Q, betweenit and :the bottom of l). The superheated steam passes through pipe L and O *into aV coil, P,within= the still, and finally passes out through a pipe, P', and is conduct'- ed to the steam-spacefQ, where it heats the bottom of the lower partB of lthe still, and is allowed to `escape eitherthrough pipe q or through the" steamlspaee between the dislV lcharge-pipe S and its `outer jacket S". An`

other escape for thesuperheated steam is the serpentine coloffpipe r, which winds around the discharge-pipeS, and, heating it, prevents j the matterlfrom discharging through the lat# `ter to coagulate it.l Steam also enters the interionof thestill through the annular exteriorfpipe M, from fwhichylextend eight Kor any *Kother suitablenumberbf pipes, Ninto the y still, each providedfon the outside with a'stopcock,iN".` On the inside of the still the pipes `pass downwardly outside" or inside of coil P, C being slightly bent so that their rosette ends,

which are provided with a number of perforations', convergetoward` the" center at the bots "torn `of the still, Af y means of` a screw-rod, j ,j j `bottom of `the still, and through it the refuse alte, T, operated by opens or closes the of the still can be drawn out. The domeof i i `the still is closedby agcap,2E, from just below `which the pipeextends, entering@ into the wormtube G, in the shape of a worm, passing out at the bottomand ending in the top of a.

vacuum-chamber, N,iwhich latter also communicates with an air-pump, M', through the chamber Q by means of a pipe, m, and is provided at the opposite end with a dischargepipe closed by a suitable cock. V is a glass tube on the front of vacuumchamber N, com` `municatingiwith thesarne :near its top and bottom, and which indicates the amount of duid in the chamber. His a reservoir used in the distillation of oil from pine wood.' The liquid turpentine in its crude state produced from the wood is conducted to this reservoir, from which it flows through a coil, J', within a vessel, J, into the still, as shown in Fig. 2. A oating bulbfvalve, a', regulates the how from the reservoir H into the coil J', while a stop-cock, K, in the part Lof coil J', in combination with bulb-valve a', may be made to so regulate the iiow of the crude turpentine that only sufficient enters the still through pipe L' to equalize the amount of distilled vapors which passes out through pipe F; '.lheV

Worm-vessel J is situated a little lower than the top of worm-tub G', and a bent pipe, I,

connects the interior of tub Gr' with the interior of vessel J in such a manner that the vessel J will be automatically filled and kept full ot' hot water from tub Gr', thus heating coil J' and the turpentine, Ste., flowing through. 5 is a iilter, provided nea'r its top with an opening, d', which is situated just below the open ing of discharge-pipe S. ln this filter a coil of pipe, d, is suitably arranged, which connects with the steam-pipe L, and is supplied through the same, cross-pipes E connecting the several bends of the coil. The iilter is also provided with a hinged bottom, f, consisting of two iron disks about two inches apart from each other and connected to each other by a series ot' short pipes set in both plates, through which the ltered matter escapes. 0n the upper disk rests a perforated sheet-iron disk, over which is stretched a piece of coarse linen, forming a tight joint on the inside of the filter. A steam-pipe, h, admits steam between the two disks of the bottomf, which latter is provided with a suitable number of ears or lugs, g, which correspond with a like number of similar lugs on the outside of the lower edge of the `filter,

e; rianne for the admission of steam into the filter, and

c is a steam-escape pipe. o, in the upper part A of the still 3, is a man-hole, the cover of which is provided with a circular piece of thick glass, to allow the operator to look into the still to enable him to regulate the admission of steam through pipes N. There may be as many of these manholes applied as may be deemed necessary or advisable. The pipes N admit the steam in many fine streams, with great force, thoroughly permeating the mass to be distilled, and continually agitating it, and at the same time heat the entire mass, aided at the bottom by the steam-space Q.

Vhen the residue is Withdrawn through pipe S the steam-coilfr and steam in the space around it prevent the matter iiowing out from coagulatin g.

Having thus describedV my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The pipes N, provided with perforated heads, and arranged Within the still, substantially in the manner described.

2. In combination with the pipes N, the outer encircling-pipe M, provided with stop-cocks for pipes N, substantially as described.

3. In distilling apparatus, the reservoir H, Worm-vessel J, coil J', and pipe L', arranged and combined to operate substantially as described.

4. In combination with the next above, the bulb-valve a in reservoir H, and stop-cock K in pipe L', to equalize the iniiux of matter to be distilled With the efflux of matter distilled, substantially as described.

5. In combination with Worm-vessel .I and Wornrtub G', the pipe I, when arranged to operate substantially as described.

6. The serpentine pipe 1 around the discharge-pipe s, substantially as and for the purpose set' forth.

7. In combination With a distilling apparatus, a iilter, 5, constructed and arranged substantially as herein described.
